Kaveri APU Features 20% CPU and 30% GPU Performance Uplift Over Richland

[NostaSeronx]

That cannot be SR core since we now know 100% that SR-B core has 16KB dedicated L1 data caches. The module in this image was disected by Hans and a few other people and they stated the data cache structure looked doubled and was now 32KB per core.

If it does come out to be 16KB, it could be that AMD decided to finally use 8T SRAM or 10T SRAM structures.

Actually, I think Seronx's SR version would be less performing, cutting clocks in half in order to double almost everything in the Integrer/FPUs. Going 2x wide doesnt necesarily mean 2x IPC in real world scenarios.

From what I can gather the scheduler and retirement queue has been enhanced. For both the x86 cores and x86 FPU.

The something weird about it anyway. Obviously they know exactly what the performance of final silicon is as they are shipping it.

They're not shipping mobile Kaveri, are they? Microarchitetures have a bit of a bell curve when it comes to efficiency at certain power envelopes. If Kaveri manages to get a 20% uplift on the desktop at the same TDP, mobile may not be less, or it could be better.

As you know, this is a recent slide. If they state it's a pre-silicon projection, then this is almost undoubtedly a valid statement today. So it would appear that as of right now, they don't know exactly what frequencies the mobile SKUs will ship at. At any rate, they should have a pretty good idea, and the margin of error would be relatively small at this point.

If it does come out to be 16KB, it could be that AMD decided to finally use 8T SRAM or 10T SRAM structures.

Really, the chance of it being SR is very minimal. It is very doubtful that AMD would have large structures like the 256 bit FPU sitting there disabled. And we know it isn't enabled on Kaveri.

Yeah I didn't realise they were referring to mobile at first, my bad.

I'm just happy to FINALLY see graphics card quality being built into the cpu. I'm a fan of silent video cards. (but being a silent video card fan doesn't make sense The last one I got was about a year ago, and I believe that the Radeon 6570 was about the best silent card you could get at the time.

I decided that the next time I upgraded, I wanted to get a system where the video would be built in to the cpu, and it should exceed the 6570 in ability. Later, that would make it easy to upgrade the cpu and video at the same time.

The fm2+ platform and Kaveri seem to be the first time that this has been achieved. I'm going to upgrade an old Intel dual core system that has the Radeon 6570, as well as an AMD system that has onboard Radeon 4250 graphics. I expect that last one to seem like a REAL upgrade, since the graphics on that even get bogged down sometimes doing casual games on armorgames. I think I'll be going from about 45 Gflops to around 850 Gflops with the Kaveri upgrade - well worth it.

Plus, since this will be built into the processor, it won't require an additional fan. For all practical purposes, this will be the same as buying another fanless 6570, but with better performance.

You can get a passively cooled HD7850.

Gibbo has desktop Kaveri now. Looks good for a real launch in Jan/Feb.

Got these beauts on my desk, shall get round to testing them soon.

 

[mindbomb]

idk if it has been mentioned, but kaveri's gpu has an h265 decoder and encoder?
http://developer.amd.com/community/blog/2013/11/11/media-sdkv1-0-beta-release/

 

[mikk]

Where do you read H.265? Kaveri has a dedicated encoding unit called VCE with h.264 support, every GCN has it.

 

[OCGuy]

OP the threads you start in the tech forums are Press-Release in nature......and you don't seem to stick around and discuss.....

What is the deal?

idk, i saw this slide http://image.slidesharecdn.com/fina...22150-phpapp02/95/slide-15-638.jpg?1384244592 , so I thought it was announced or something. it might just run on the shaders and work on any gcn card though.

How bout looking into a specialty card. I've seen a couple passive cooled Radeon 7850s around, and they will blow away Kaveri many times over.

 

[Qwertilot]

The review I saw recently of a passive 7850 seemed to think it was slightly marginal whether the passive cooling was really quite enough for such a 'big' card. (7750's definitely, 7770's I don't know about.).

Looks worth waiting for 20nm if possible because that should make for a sensibly passively cooled card which can keep up with the consoles.

Mind you, I'd have though that most passive graphics card fans would also ideally be after a passively cooled CPU too.

The only people with a 'realistic' chance of producing a passive CPU/dGPU with decent graphics performance would be Intel. Not easy and likely horribly expensive if they do of course.

 

[krumme]

There is a pretty long and good thread imho about kaveri at SA for those interested.

It might be long, but as for good, well . . . . . . :awe:

The fact that it says "Must stay programmable" implies that it is run on the GPU, not the UVD block.

lol, harsh. It has plenty of interesting technical nuggets in there, even if there's quite a lot of... enthusiasm.

New roadmap. Excavator tops out @ 65W TDP (just like Digitimes pointed out months ago), Beema looks like a H2/2014 product (no successor in 2015?).

Shame that Excavator is going for efficiency, not balls-to-the-wall performance. I guess it's more likely to get them into laptops, which is where they need to be... but it also means I may not be replacing my Kaveri, when I make my HTPC.

Isn't that the trade off for HDL?

AMD tried balls out performance with the fx 9-series, have you forgotten how much it has been panned...

You mean kind of like Anand's forums have become?? Seems to be a lot of "enthusiasm" going around lately.

 

[NostaSeronx]

The fact that it says "Must stay programmable" implies that it is run on the GPU, not the UVD block.

The parts that can't be paralellized might as well be run on the UVD block for decoding and the VCE block for encoding. Where the sections that can technically scale infinitely be run on the CUs.

Isn't that the trade off for HDL?

Steamroller uses HDL as well.

The problem with the 9-series was not really that it was aimed at performance, but it was basically just a binned (we assume) and overclocked 8350 with a high price tag.

Some infos provided by AMD itself.

To begin with, Adam Kozak, AMD's marketing chief for client processors, told folks during a press briefing that Kaveri will be competitive with Intel's Core i5-4670K processor.

On the subject of power consumption, Kozak wouldn't give us definite numbers, but he told us that he expects Kaveri to consume less power than the Core i5-4670K at idle and to draw more power under load. Earlier in the briefing, Kozak had mentioned that Kaveri would have a similar target TDP to "what you see today on the A series."

TR estimate the price to be about 140$ from the infos they got.

Why did you not give the rest of the quote?

"When pressed for details after the briefing, however, Kozak clarified that Kaveri should only be equivalent in terms of combined CPU and GPU compute power. If one measures x86 performance on its own, Kozak said, "we'll lose." However, Kozak expects Kaveri's integrated graphics, bolstered with Mantle support, to be better than the latest version of Intel's HD Graphics."

Richland's igp is already ahead of HD4600, so I dont see anything game changing there.
